Rated capacity 525kVA

Rated voltage 690V

Basic Information:

Type: Three-phase phase module.
Rated Capacity: 525kVA.
Rated Voltage: 690V.

Product Features:

High Efficiency and Energy Saving: Compared with previous phase modules, it has higher efficiency, helping to reduce energy loss and improve the overall energy efficiency of the system.
Compact Size: Occupies a small space with a minimal footprint, suitable for installation in areas with limited space and convenient for system integration and layout.
Easy Installation and Maintenance: The design facilitates installation and maintenance, reducing installation time and maintenance costs while improving equipment availability and maintainability.

Working Principle:1. Rectification Stage (AC→DC)

Input Side Processing:
The module receives 690V three-phase alternating current (from the power grid or transformer) and converts it into direct current through a silicon controlled rectifier (SCR) or IGBT rectifier unit.

The rectification process adopts multi-pulse rectification technology (typically 12-pulse or 24-pulse), significantly reducing harmonic interference and increasing the power factor on the grid side (>0.95).

DC Link:
The rectified direct current is filtered by a DC bus capacitor to form a stable DC voltage, providing energy buffering for the subsequent inversion stage.

2. Inversion Stage (DC→AC)

Output Side Control:
The DC voltage is inverted into three-phase alternating current with adjustable frequency through an IGBT (Insulated Gate Bipolar Transistor) power module to drive the motor.

The inversion process uses Direct Torque Control (DTC) technology or Space Vector Pulse Width Modulation (SVPWM) to achieve precise control of motor torque and speed.

Frequency and Voltage Regulation:
By changing the frequency (typically 0-120Hz) and voltage (0-690V) of the output alternating current, stepless speed regulation of the motor is achieved to meet different load requirements.

3. Phase Control and Protection

Phase Synchronization:
The module is equipped with a built-in phase detection circuit that real-time monitors the phase difference between the grid and the motor to ensure maximum energy transmission efficiency.
Protection Mechanisms:
Integrates multiple protection functions such as overcurrent, overvoltage, undervoltage, and overheating, responding quickly to faults through intelligent sensors and control algorithms to protect equipment safety.

III. Technical Features and Advantages:

High-Efficiency Energy Conversion:
Adopts advanced power semiconductor technology (such as IGBT) with a conversion efficiency >98%, reducing system energy consumption.
Low Harmonic Interference:
Multi-pulse rectification design reduces harmonic current (THD
Precise Control Performance:
DTC technology provides millisecond-level dynamic response, with torque control accuracy reaching ±1%, suitable for high-precision industrial applications.
Modular Design:
The phase module features a compact structure and supports hot-swapping, facilitating on-site maintenance and upgrades.

Application Fields:

Power Industry: Used for high-voltage motor drives, such as driving boiler fans, induced draft fans, water pumps, etc., in power plants, as well as power conversion for wind and solar energy in renewable energy systems.
Oil & Gas Industry: Suitable for driving and controlling equipment such as compressors, pumps, and fans in oil drilling platforms and refineries.
Metallurgy & Mining: Can be used to drive mining equipment such as crushers, conveyor belts, and winches in concentrators, meeting the power demand of these high-load devices.
Chemical & Pharmaceutical Industry: Frequency conversion control of large mixers, centrifuges, fans, and compressors, helping to achieve precise process control and energy-saving operation.
Other Industries: In industries such as cement & building materials, paper & textiles, and rail transit, it is used to drive equipment requiring high-efficiency energy conversion and precise motor control, such as kiln blowers, press machines, and train power drive systems.
